PROBLEM TO BE SOLVED: To provide a charge/discharge inspection device capable of materializing energy saving.SOLUTION: A charge/discharge inspection device 2 is configured so that (i) during power running, an AC voltage from a commercial AC power source PS is converted to a DC voltage, and the DC voltage is stepped down to charge a secondary battery 1, and (ii) during regenerating operation, the voltage of the secondary battery 1 is stepped up, and the stepped-up voltage is converted to an AC voltage and can be restored to the commercial AC power source PS side. Among paths from the commercial AC power source PS to the secondary battery 1, the length of wiring used in a path where an effective voltage level is the highest is made longer than the length of wiring used for other paths. |
